DIE FOR BOX-STAYING MACHINES.

SPECIFICATION forming part of Letters Patent No. 648,638, dated May Application filed December 21, 1899. Serial No. 741,077. "No model-l lie it knownthat l, llARRYli. SMITH, aciti- Zen of the U11 ited States, residing at New York, (.Hrooklym) in the county of Kings and State of New York, have invented certain new and useful lmprovcmentsin Dies for Box-Stayin g Machines; and I do hereby declare the following to be a full, clear, a nd'exact desoription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to machines for applying the corner-stays to' the edges of paper boxes; and it has for its object to provide an improved die for use in connection with such machines by means of which the corner-stays may be readily, accurately, and expeditiously applied to the corners of boxes having extended bottoms-tl1at is to say, boxes the bottoms of which project laterally beyond the sides of the box.

It also has for its. object to provide a die of the character described that is adapted to apply the corner-stays to boxes of different heights.

To these ends my invention consists in a die constructed and operating in the manner hereinafter described and particularly pointed out in the claims following the description, reference being had to the accompanying drawings,- forming'a part of this specifi-' cation.

For the purpose of more clearly explaining the construction and purpose of my improved die and the manner of using the same I have illustrated such portions of a well-knowntype of box-jointing machines as appears tobe necessary or best suited for the purpose, the machine selected for the purpose being that shown in the patent to M. D. Knowlton, No. 447,955, and dated March 10, 1891. It will be understood, however, that said machine forms no part of this invention, which resides entirely in the die, and that said die is equally well adapted for use in various other well-- known machines of the same general type or in any machine which may be preferred and v which is suitable for thepurpose in hand.

I will briefly describe so much of said machine as will benocessary to explain the operation of my improved die and the-constructical face of the frame.

tion of the latter, in detail, reference being had to the accompanying drawings,wherein Figure l is a vertical sectional view of a portion of the machine. Fig. 2 is a front clevation of a portion thereof, showing the box in position for receiving a corner-stay.' Fig.

3 is a detail perspective view of my improved die. Fig. 4 is an -end view of my improved die constructed to apply stays to boxes having round corners and showing the anvil for receiving the impact of the die. Fig. 5 is a detail perspective view of a modification showing the die made in sections, and Fig. 6 is a detail sectional view showing the manner of securing the sections of the die in place on the machine. 1

In the type of machine herein illustrated a stationary anvil is employed, over which the corners of the box are successively placed, while the clamping-die is arranged to reciprocate above and toward and from the-anvil, the strip from which the corner-stays are made being fed endwise between the die and anvil and is severed into proper lengths by acutting edge formed'on, the end of the die, acting in conjunction with a stationary die-cutter. The anvil is adjustable endwise with relation to the frame of the machine and the die-cutter, so as to accommodate itself to boxes of different heights.

' Referring to the drawings, the numeral 1 indicates the frame of the machine, and 2 the anvil, constructed in the form of a rod or bar and supported horizontally in the frame of the machine, as most clearly shown in Fig.

1 and 2 of the drawings. The anvil extends at itsouter end through and beyond the frame 1 and is secured therein by any suitable means, so that it may project more or less to' any desired distance beyond the vershown the anvil is made semicircular on its under side and is provided on its upper side with flat working faces 3, arranged at right angles to each other, with their apex or meeting edge'nppermost. I

In the construction The numeral 4 indicates the die, consisting of a rod provided on its underside with a longitudinal \lsshaped groove 5, correspond 'ing in configuration. and dimension to the angular working face 3 of the anvil. The

I! the die when the latter descends.

die is grasped and rigidly secured in a vertically-movable support constructed as follows:

The numeral d indicates a block having a longitudinal groove or recess7 formed in its under side, said groove or recess being par tially cylindrical in cross-sectionthat is to say, the walls of the groove or recess are formed on the are of a circle of approximately two hundred and seventy degrees, orat least greater than one hundred andeighty degrees.

. The block is split or divided centrally in line 4 with said groove or recess, as at 8, and passing transversely through said block ajrescrewsQ. The die a isinserted endwise in the groove or recess 7 of the block and is prevented from turning axially therein by ascrew 10, which is screwed into the end face of the'block and projects into a groove 11', formed in the upper side of the die.- After the lie has'been inserted in the block the screws 9 are tightened up, thereby tightly clam ping the die in place. carried by a The block is attached to and slide 12, arranged to reciprocate vertically in suitable ways formed in a head-bl0ck 13,'snpported on the frame of the machine. i The slide is reciprocated by a pivoted bell-crank lever .14, oscillated by any suitable means, the. short arm of said bell-crank lever being "loosely fitted in a slot 15, formed inthe slide. *Fixediover the inner portion of the anvil 2 is an'inverted-V-shaped die-cutter 16, so arranged relatively to the reciprocating die 4.- that the outer end of the die-cutt'erwill lie in close proximity to the inner or rear end of :In practice the sides of the corner of the boxto. be stayed are placed on the anvil 2,1

with-thebottoinof the box resting against the end of theanvll. v- The stay-stri p 17, which may consist either jot a metallic or paper. strip or tape, is fedendwise between the die and anvil either by hand or, any suitable feed. mechanism and the die caused to descend/.1-

As the inner or rear end of the die moves past the face of the die-cutter 16, it shears off or severe the stay from the strip or tape, and the die immediately thereafter forcibly presses the staydown upon and about the corner of the box supported'on the anvil. If

I the paper stay is employed, it will have a suit- -devices Will be pro'videdas,

' trate "the sides of the box and the manner above described are old and'well known and form no part of the present invention, but must necessarily be clearly'uirderstood in order to fully understand the pur- -to boxes of diiferent sizes.

to the other pose and operation of my improved die, which -I will now describe. f

A die constructed as above described is not suited for applying corner-stays to boxes having extended or laterally-projecting bottoms, as shown in Figs. 1 and 2, wherein the num er'al 18 indicates the laterally projectingbot tom of the box, and 19 the sides of the latter,

owing to theliahility of the die upsetting,

mashing down, or otherwise distorting or inju-rying the projecting portionofithe bottom of the box, and inorder-toadapt the die to.

such boxes I form] a transverse slot or mortise 20 in the under sideof the die, which intersects the V-shaped groove 5 and forms a recess into which the extended portion-of the bottomof the box is adapted to project without touching any portion'of the die and which permits the working. faces of the die to en-.

gage and forcibly press the, stay aboutthe,

corner of the box. throughout the" length of.

the box, thereby avoiding allinjury to the extended bottom of thebox; As shown most clearly in Fig. 2 of the drawings, theatransverse slot or mortise 2Q ex-tendsto at least the center ofthe die, while the bottom of. the V- shapedgroove doesnot extend to the'center,

thereby affording room forthe corners of the extended bottointo enter the recess without coming in contact withthe'bo'dyioh 'the die.

As most clearly shown in'Figs. 1"and 3, the

slot or mortise 20 is formed inthe dieinter mediate the longitudinal cen lcrfof the latter and one of its ends, thereby dividing the dieinto two portions of unequal length, by which arrangement the die is adaptedto apply stays to boxes of two diiferent depths or having sides of two different heights. It will be evident that when the die is arranged as shown in Fig. 1 the die will operate to cut off a stay from the strip" 17 and apply it along -'the'e'ntire length of theco'rn'erof-a box the sides of which are coextensive Withthat'portion of the die extending from thereeess 20 to the inner endof-the, dieiand' that the extended portion of the'bottonrl8 of the box will project into said recess, and thereby escape injury. ,By removingthe die,-revers ing it'end' for end, replacing it, and then'adjustingtlie anvil 2 in ward the machine is adapted for applying stays to boxes the heights of which are equal to the shorter portion of the die in manner the same as that beforedescribed. In this'manner the same die may be employed for severing the stays and for applying them In Figs. 5 and 6 I have shown amodified construction of die, wherein instead of making the die .i'n-a single integral piece i,t-is made inseparate sections. Referring to said figures, the numerals 21 and 22 respectively indicate the two sections of the die, each hav- 1 ing the same general configuration as the die. before described,- but of less length, the two sections being of unequal length,'a s shown in Fig. 5. Arranged between the adjacent ends ot the sections 21 and 22 is a distance- I I shaped groove block 23'of the same general shape in crosss'ection as the said sections having the V- out deeper therein than in the sections, whereby when the parts are assembled to form a complete die a V-shaped recess 24 is formed between the adjacent and correspondingly shaping the groove in' ends of the 1ie' corresponding to the recess 20,'before described, and in which the exthe. bottom of the box' tended portions of are adapted to project. The die-sections are seeured'ina block 6 in thesame manner as the die 4, before described, the screw 10 in this form of the device extending along substantially the, entire length of the dieto permit the reversal of the sections. By removing the die-sections and reversing to end it is evident that the die will be suited to boxes of different sizes in the same mannor as the die 4'.

, It will be obvious that stays may be ap-' plied toboxeshaving rounded corners by.

making the Working face of the anvil rounded Fig. 4:.
